  • Storage startup trends: Vendors to watch in 2018

    Another year is behind us, and 2017 wasn't kind to enterprise-storage startups, as a bunch went belly up or sold off their assets. Not deterred by this recent history and startup trends, a new group of companies has emerged to try and make an impact in 2018. These include Aparavi, Attala Systems, Elastifile, Minio, Morro Data, Vexata, Wasabi Technologies and WekaIO. They have products focused on hot storage sectors, such as flash, hybrid cloud, scale-out file systems and object storage. Who's behind these startups? What do they offer that the market doesn't already provide? And, given recent startup trends, what are their chances for success? Find out with an early look at these upstarts.

    A server still looks like a server, and network cables and racks haven't changed much over the last couple of decades, but storage has fundamentally transformed. Disk has lost its crown as the king of primary storage and is becoming relegated to the secondary -- and even cold -- storage world. More significantly, the data center is becoming more software-defined. That means storage functions that once demanded specialized hardware now reside in adaptable, pliable, reprogrammable and easily updateable software constructs. Explore the state of the software-defined storage market.

    The advent of virtualization and its need to share all resources threatened the relevance of direct-attached storage (DAS) -- storage within the server. Only the emergence of flash storage, most specifically PCIe SSDs, staved off DAS' extinction, with the likes of Fusion-io demonstrating what you could do with high-speed flash integrated in the server. Today, storage is about to move even further into the server thanks to advancements in storage-class memory -- also known as persistent memory -- technologies. Here's how, why and what this development could mean to you.

  • Disaggregation enables on-demand resource pool management and creation

    Disaggregation may not be a new concept, but it has become more important to IT in recent years. Here, it means breaking computers down to the core elements of compute, memory, I/O, storage, cache, network fabric and so on, to enable resource pool management and create more agile, cost-effective data centers. Done correctly, disaggregation lets you stand up and break down infrastructures almost instantly while better serving the needs of individual applications. Meanwhile, resource utilization soars, and resource pool management costs decline because of the automation that's enabled. Delve into the world of disaggregation and find out how vendors are applying the concept to their products.

    Hybrid cloud storage can let you run, manage and move primary storage workloads between the cloud and on-premises data center. It can also improve IT agility and cut costs. Today, a number of products and services fulfill the promise of the hybrid cloud like never before, knocking down barriers that have inhibited wider adoption. Hybrid cloud products open new possibilities for deploying production applications, but you must choose wisely.

    Pundits have predicted the demise of the hard disk for years. Not only is solid-state much faster than hard disks, the price differential between the two storage technologies is rapidly disappearing. Yet the HDD vs. SDD controversy continues with the death of the former still a long way off. The question shouldn't be when hard disks will disappear, but instead, how to best use flash technology within the memory-storage continuum that starts with tape and goes to L1 cache, the fastest and most expensive memory in a system.
